The twoside walls 3235 are formed by respectively bending two sides of the tophousing 3231, which extend towards the bottom housing 3211. The two sidewalls 3235, the top housing 3231 and the bottom housing together form anaccommodating cavity 3237 and the accommodating cavity 3237 is used topartially accommodate the second clamping member 34. A mounting hole3239 is located on and penetrates one of the two side walls 3235. Themounting hole 3239 is located at the end of the corresponding side wall3235 which is far away from the first clamping part 3233 and is used tomount a part of the structure of the limiting assembly 38.

The first protecting member 325 covers the top housing 3231 and thesurface of the first clamping part 3233 facing away from the remotecontroller body 201, and is used to protect the clamped displayingdevice from scratches. In this embodiment, the first protecting member325 is made of an elastic material. In particular, the first protectingmember 325 may be made of foam. It is understood that the firstprotecting member 325 can also be made of another elastic material, suchas rubber.

The second clamping member 34 is partially and movably inserted in theaccommodating cavity 3237, and comprises a moving part 341, a secondclamping part 343 provided on one end of the moving part 341, and asecond protecting member 345 provided on the second clamping part 343.

Please refer to FIGS. 7 and 9, the moving part 341 is approximatelyrectangular plate and is accommodated in the accommodating cavity 3237.A limiting part 3411 is formed on the side of the moving part 341 facingtowards the mounting hole 3239. In this embodiment, the limiting part3411 is in a sawtooth rack shape and is used to snap with the limitingassembly 38 so to limit the mounting position of the second clampingmember 34 relative to the first clamping member 32. The moving part 341is also provided with a meshing part 3413 on the side facing towards thebottom housing 3211, and the meshing part 3413 is formed correspondingto the meshing member 3219. In this embodiment, the meshing part 3413 isa rack meshing with the meshing member 3219. When the moving part 341slides relative to the first clamping member 32, the meshing part 3413meshes with the meshing member 3219, such that the sliding is smootherand resistant to shaking.

The second clamping part 343 is provided on the end of the moving part341 which is far away from the first clamping part 3233 and faces thesecond clamping part 343 in a parallel manner. The second clamping part343, the first clamping part 3233 and the top housing 3231 together forma clamping space (not marked in the figures) for accommodating thedisplaying device. Under the action of external force, the secondclamping part 343 can move relatively away from or close to the firstclamping part 3233, such that the holding mechanism 30 can holddisplaying devices of different sizes.

The second protecting member 345 is provided on the side of the secondclamping part 343 facing towards the first clamping part 3233, and thematerial and function thereof are approximately the same as the firstprotecting member 325. In order to avoid redundancy, details will not berepeated herein in the description.

The first elastic member 36 is provided between the moving part 341 andthe top housing 3231, one end thereof is connected to the bent part 3213and the other end is connected to the second clamping member 34. In thisembodiment, the first elastic member 36 is a compression spring. In anoriginal state, i.e. when the moving part 341 is almost completelyaccommodated in the accommodating cavity 3237, the first elastic member36 is in a compressed state. When the second clamping part 343 of thesecond clamping member 34 moves towards the direction away from thefirst clamping part 3233, the first elastic member 36 is graduallystretched to store elastic energy, so as to provide a restoring force ofmovement to the second clamping member 34.

Furthermore, the first clamping member 32 further comprises a thirdclamping part 327, and the third clamping part 327 is rotatablyconnected to the first housing 321 or/and the second housing 323. Whenthe third clamping part 327 rotates to the position perpendicular to thefirst housing 321 and/or the second housing 323, a clamping space forclamping external devices such as a tablet computer or a mobile phone isformed between the third clamping part 327 and the second clamping part343.

In particular, in the embodiments as shown in the figures, the thirdclamping part 327 is rotatably connected to the second housing 323 via apivot shaft, and an accommodating groove for accommodating the thirdclamping part 327 is provided on the second housing 323. When the thirdclamping part 327 rotates to the position perpendicular to the firsthousing 321 and/or the second housing 323, the third clamping part 327abuts against the side wall of the accommodating groove facing thesecond clamping part 343.

The specific structures of the third clamping part 327 can be designedaccording to different requirements, for example, in the embodimentsshown in the figures, the third clamping part 327 is a clamping hook andcan be snapped with an external devices such as a tablet computer or amobile phone to prevent the external device from falling off.

Please refer to FIG. 10, the limiting assembly 38 is provided on thebottom housing 3211 corresponding to the mounting hole 3239 and is usedto be snapped with the limiting part 3411, so as to limit the mountingposition of the second clamping member 34 relative to the first clampingmember 32. The limiting assembly 38 comprises a pivot shaft 381, alimiter 383 rotatably sheathed on the pivot shaft 381, and pressingmember 385 and the second elastic member 387 both provided on thelimiter 383.

The pivot shaft 381 is fixedly provided on the top housing 3231 andclose to the limiting part 3411 on the moving part 341. The limiter 383is an approximately bent block shape and the approximately middleposition thereof is rotatably sheathed on the pivot shaft 381. Under theaction of an external force, the limiter 383 can rotate around the pivotshaft 381. In this embodiment, the limiter 383 is a rotating stir wheelwith one end thereof being snapped with the sawtooth rack of thelimiting part 3411 and the other end thereof being as operating end.Particularly, the limiter 383 comprises a rotating part 3831 and apressing part 3833 formed on one end of the rotating part 3831. Therotating part 3831 extends from the pivot shaft 381 towards the limitingpart 3411; the pressing part 3833 extends from the pivot shaft 381towards the mounting hole 3239; and a certain angle is formed betweenthe rotating part 3831 and the pressing part 3833. The end of therotating part 3831 which is close to the limiting part 3411 protrudes toform a stopping part 3835. In this embodiment, the stopping part 3835 isin a protruding tooth shape and is used to snap the saw teeth of thelimiting part 3411. The pressing member 385 is mounted in the mountinghole 3239 with one end being abutted against the pressing part 3833 ofthe limiter 383 and the other end protruding out of the side wall 3235.One end of the second elastic member 387 is connected to the pressingpart 3833 and the other end is connected to the top housing 3231. Inthis embodiment, the second elastic member 387 is a helical compressionspring.

When the pressing member 385 is pressed by an external force, thelimiter 383 is driven thereby to rotate around the pivot shaft 381, suchthat the second elastic member 387 elastically deforms and iscompressed, and at the same time, the pressing part 3833 brings thestopping part 3835 to move away from the limiting part 3411, thereforethe stopping part 3835 is no longer snap-fitted with the limiting part3411, and the second clamping member 34 can move relative to the firstclamping member 32. When the external force is lifted and under theaction of the elastic restoring force of the second elastic member 387,the limiter 383 rotates reversely around the pivot shaft 381 and thestopping part 3835 is again snapped in the limiting part 3411, such thatthe second clamping member 34 is fixed relative to the first clampingmember 32.

When assembling the bracket 100 in this embodiment, firstly, thelimiting assembly 38 is arranged on the second housing 323 and themoving part 341 is arranged in a parallel manner on the top housing3231, such that the stopping part 3835 is snapped in the limiting part3411. The meshing member 3219 is rotatably arranged on the bottomhousing 3211; the first elastic member 36 is connected between the bentpart 3213 and the second clamping member 34; and then the first housing321 is snap-fitted on the second housing 323, such that the meshingmember 3219 is meshed with the meshing part 3413. Next, the firstprotecting member 325 and the second protecting member 345 are arrangedon the first clamping part 3233, the top housing 3231 and the secondclamping part 343. Then, the holding mechanism 30 is mounted on theconnecting frame 12 via the fastening assembly 16, and then the locatingassembly 14 is arranged on the connecting frame 12. When the bracket 100needs to be mounted on the remote controller body 201, firstly, thefastening shaft 141 is inserted in the locating hole of the remotecontroller body 201 and then the fastening sleeve 143 is screwed in thelocating hole, thereby firmly mounting the bracket 100 on the remotecontroller body 201.

Please again refer to FIG. 1, wherein in a non-use state, the holdingmechanism 30 is approximately parallel to the remote controller body201, the top housing 3231 thereof faces the remote controller body 201,and the first clamping part 3233 is partially accommodated in theaccommodating space 127 of the connecting frame 12. At this time, thefastening assembly 16 steadily fixes the holding mechanism 30 on theconnecting frame 12 and the operating member 165 of the fasteningassembly 16 is relatively close to the locking member 161.

When using the bracket 100 and the remote controller 200 of the presentdisclosure, firstly, the operating member 165 rotates to cause thesnap-fitting part 1657 to correspond to the sliding groove 1638 and thenthe operating member 165 is pulled to move away from the locking member161. When the snap-fitting part 1657 slides into the snapping part 1637along the sliding groove 1638, the operating member 165 is slightlyrotated along a first direction to enable the snap-fitting part 1657 tobe dislocated from the sliding groove 1638 and to abut against the sidewall of the snapping part 1637. The operating member 165 continuesrotating along the first direction, the operating member 165 pushesagainst the side wall of the snapping part 1637 via the snap-fittingpart 1657, such that the fastening member 163 as a whole rotates andmoves relatively away from the locking member 161, thereby enabling thetwo locking parts 3215 to be restored elastically and the connectingpart 125 clamped between the two locking parts 3215 to be released. Atthis time, the holding mechanism 30 is rotatable relative to the seat10.

Secondly, the holding mechanism 30 rotates around the fastening assembly16 until the holding mechanism 30 rotates to a required operating angle,the operating member 165 rotates along a second direction opposite tothe first direction, such that the operating member 165 brings thefastening member 163 to rotate until it is screwed with the lockingmember 161, and the fastening member 163 and the locking member 161together clamp the two locking parts 3215, thereby fixing the holdingmechanism 30 relative to the seat 10. Again, the operating member 165slightly rotates along the first direction, and the operating member 165is released after the snap-fitting member 1657 corresponds to thesliding groove 1638. Under the action of the elastic restoring force ofthe resetting member 167, the snap-fitting part 1657 slides along andmoves away from the flange part 1639 along the sliding groove 1638, andthe operating member 165 as a whole is relatively close to the lockingmember 161.

Then, an external force is applied to the pressing member 385, such thatthe snap-fitting between the stopping part 3835 and the limiting part3411 is lifted, and at the same time, the second clamping part 343 ispulled to enable it to move away from the first clamping part 3233. Atthis time, the first elastic member 36 is stretched and stores elasticenergy. When the spacing between the first clamping part 3233 and thesecond clamping part 343 meets requirements, the second clamping part343 and the pressing member 385 are released, such that the firstclamping part 3233 is fixed relative to the second clamping part 343.

At last, a displaying device such as a mobile phone, a display or atablet computer is mounted between the first clamping part 3233 and thesecond clamping part 343. The pressing member 385 is pressed again, andunder the action of the elastic restoring force of the first elasticmember 36, the second clamping member 343 is relatively close to thefirst clamping part 3233 and abuts against the displaying device. Thefirst elastic member 36 still has the tendency to recover from adeformed state to a normal state and the elastic force thereof isconverted into the clamping force for the displaying device, therebyholding the displaying device on the holding mechanism 30. The pressingmember 385 is released again to enable the stopping part 3835 to onceagain be snapped with the limiting part 3411, and the clamping part 3233and the second clamping part 343 are thus further fixed so that thedisplaying device is firmly clamped on the holding mechanism 30.

When the installation angle of the holding mechanism 30 relative to theremote controller body 201 needs to be adjusted, the fastening assembly16 is released according to the method, such that the holding mechanism30 is rotatable relative to the seat 10. The holding mechanism 30rotates to the needed installation angle, and the holding mechanism 30is once again fixed relative to the seat 10 via the holding mechanism16. Such holding mechanism 30 of the remote controller 200 of thepresent disclosure uses both the first clamping part 3233 and secondclamping part 343 to clamp the displaying device, the second clampingpart 343 can move relative to the first clamping part 3233, such thatthe bracket 100 can be applied to displaying devices of different sizesand the application range of the holding mechanism is broad. Inaddition, the holding mechanism 30 limits the distance between the firstclamping part 3233 and the second clamping part 343 by snapping with thelimiter 383 and the limiting part 3411, such that the holding mechanism30 is applicable to displaying devices with larger size differences,which further enlarges the application range of the holding mechanism.The limiter 38 and the limiting part 3411 can be firmly snap-fitted,such that the clamping from the holding mechanism on the displayingdevice is more reliable. Moreover, the installation position of theholding mechanism 30, as a whole, relative to the remote controller body201 can be adjusted via the fastening assembly 16, such that the use ofthe remote controller 200 is more flexible.

It is understood that the second elastic member 387 can be an elasticmember of another structure, for example, a torsional spring, a coilspring, an elastic plate, an elastic sleeve, etc., and one end of thesecond elastic member 387 abuts against the first clamping member 32 andthe other end abuts against the pressing member 385 to provide arestoring force of movement to the limiter 383.

It is understood that the second elastic member 387 can be omitted andthe limiter 383 may be designed with an elastic structure, and when anexternal force is applied, the limiter can be snapped with or separatedfrom the limiting part 3411. Alternatively, the limiter 383 as a wholeis arranged on the second housing 323 and can be a pluggable structure,and the stopping part 3835 on the limiter 383 is snapped with orseparated from the limiting part 3411 by inserting the limiter 383 intothe second housing 323, or pulling the limiter out from the secondhousing 323.
